Hi, this is probably your best chance -

• Profiles - Where Firefox stores your bookmarks, passwords and other user data.

• Recover important data from an old profile.

If your question is resolved by this or another answer, please take a minute to let us know. Thank you!

I have tried to do that. But I am not sure how exactly I should recover files. There is only one default profile and CC Cleaner removed all the files. Should I use a file recovery program? Thanks

I have had just another go with recovering deleted files in Mozilla's folder and I recovered History but not Tabs

For the tabs you need the sessionstore.js file.

Firefox uses sessionstore.js in the profile folder to store session data. Sessionstore.js is only present when Firefox is closed. The sessionstore.js file is created from recovery.js when you close Firefox and is removed and copied to previous.js when you start Firefox to make is possible to restore the session at any time.

You will normally find these files in the sessionstore-backups folder:

• previous.js (cleanBackup: copy of sessionstore.js from previous session that was loaded successfully)
• recovery.js (latest version of the sessionstore written during runtime)
• recovery.bak (previous version of the sessionstore written during runtime)
• upgrade.js-<build_id> (backup created during an upgrade of Firefox)

You can copy a file from the sessionstore-backups folder to the main profile and rename the file to sessionstore.js to replace the current file (make a backup copy of the current sessionstore.js).
